Philip Sterne https://2016.za.pycon.org/talks/39/ Any time you have noisy data where you would like to see the underlying trend then you should think about using Gaussian processes. They will smooth out any noise and give you a great visualisation of the error bars as well. Rather than fitting a specific model to the data, Gaussian processes can model any smooth function. I will show you how to use Python to: fit Gaussian Processes to data display the results intuitively handle large datasets...

Armin Rigo https://2016.za.pycon.org/talks/42/ RevDB is an experimental "reverse debugger" for Python, similar to UndoDB-GDB or LL for C. You run your program once, in "record" mode, producing a log file; once you get buggy behavior, you start the reverse-debugger on the log file. It gives an (improved) pdb-like experience, but it is replaying your program exactly as it ran---all input/outputs are replayed from the log file instead of being redone. The main point is that you...
